His prices were very good and he sent his instaler out that week to get accurate measure of the windows to be replaced.

They not only fixed the sliding door but also fixed a screen and window handle and asked if I had any other window / door problems . Wow what service ! I would definitely recommend this company . Very polite and prompt too."

"Excellent workmanship and products I have had three installations with Power in the past two years. I first used them for a new roof and gutters. The workers were all knowledgeable in their area of work. Clean up was good although some nails kept showing up over time. Next I had the 2nd floor windows and some 1st floor windows replaced, 9 in total. Installation went well and they cleaned up beautifully afterwards. I love the windows! They are a beautiful and energy efficient product. Lastly, I recently had a bay window replaced in my kitchen with the same type window. The workers ere all friendly and explained what would be done. The area was draped with plastic to cut down on dust. Clean up was excellent inside and outside! The window is beautiful and the framing on the outside of the window matches the other windows and the small roof above the bay window was replaced with the same roofing as the rest of the house. I would choose them again for any future projects."

"I recently had my window seal failures repaired, and the difference is night and day. Before the repair, I was dealing with foggy glass, drafts, and noticeable temperature fluctuations—especially during colder days. It not only looked bad but also made my home less comfortable and likely less energy efficient. The repair process was smooth and professional from start to finish. The work itself was completed efficiently, and Jon took care to keep everything clean and protected during the process. Now, my windows are crystal clear again, and the insulation has noticeably improved. There are no more drafts, and the rooms feel more consistent in temperature. It honestly feels like an upgrade to the entire house. If you’re dealing with failed window seals, I’d definitely recommend getting them repaired sooner rather than later—it makes a bigger difference than you might expect."

"I am so grateful that I saw a review for a company that could replace the glass on our sliding door. It had hazed so badly we could barely see through it. Ahmed responded swiftly to my query, set up a convenient, masked, appointment, and gave us a 2 week completion date for a price that was much better than the cost of replacing the whole unit. Well, it was finished in less than 2 weeks, and he came over this morning ~ and oh my heavens, it is beautiful. After years of hazy glass, it's almost a miracle! The replacement was done with great care, and everything was cleaned up perfectly afterward. Wonderful experience...Highly recommended."
